REFRlGERATOR-CAR.

SPECIFICATION forming part of Letters Patent No. 348,840, dated September 7, 1886.

Application tiled March 22, 1856. Serial No. 196,116.

T0 all whom, it may concern.-

Be it known that I, CHARLES HAnIvoKn, of the city of Baltimore, State of Maryland, have invented certain Improvements in Refrigerator-Cars, of which the following` is a specilication.

This invention relates to certain improved means for eiTeeting a circulation of air in a railroad refrigerator-car, as will hereinafter fully appear.

In the drawings, forming a part hereof, Figure I is a longitudinal section of a refrigerator'car provided with my improvements. Fig. II is a cross section of Fig. I, taken on the dottedliue .t fr. Figs. III, IV, V, and VI are details of the invention on an enlarged scale.

A is the ear, a a, which are separated ear by the partitions b These partitions have holes c c near to the bottom, to admit of cold air from the ice-compartments Flowing to the body of the car.

B B are salt-receptaeles, formed of wire- Work, and similar to those described in Letters Patent No. 343,369, granted to Ine on the Sth day of June, 1886. The salt serves to absorb moisture and produce a saline atmosphere in the ear, which tends to preserve having the iceeompartments from the body ofthe meats and other perishable goods placed therein.

C and D are air-pipes leading from near the bottom of the car to a chamber, E, situated in the top of the car. This chamber is open (No model.)

at the bottom, and provided with a turbine, d, ou a central shaft, e, which is revolved by means of a fan, f, operated by the wind or the motion of the ear. Dampers g and hare used to ont off the current in either off the pipes C and I).

Then the fan or turbine is in operation, warm air is taken from near the top of the car and forced through either or both the pipes C and D to near the floor, when it mingles with the cold air situated at that point. By this movement of air the entire atmosphere of the ear is brought to a uniform temperature and in contact with the salt contained in the receptacles B B.

Vhile I have described the circulation of air as heilig in a refrigerator-ear, it is evident that any preserving or other chamber can be provided with the circulating apparatus described by slightly modifying the details of its construction and the arrangement ot its parts. In some eases the turbine will have to be driven by some suitable motor, such as a steam or water engine.

In a refrigerating room or chamber, pipes leading from the lower to the upper part thereof having therein an air-circulating turbine, substantially as and for the purpose specified.
